"Where there are insufficient assets to provide for a Clean Break, however, such that the assets are divided fairly between the parties, I posit the question as to why it is fair that the asset of economic generation is not divided according to fairness but is defined by the reasonable requirements of the economically disadvantaged party – however generously assessed? If economic generation is an asset of the parties borne of the decisions that they have made in their relationship, why is it not susceptible to a percentage division as any other asset would be? Clearly, the appropriate percentage division of that asset should reflect the continuing contribution to it by the economically dynamic party but is the anchor of reasonable requirements an appropriate method of division of an asset to which both parties have contributed equally to the creation of during the marriage?"

Love the way it's assumed that the wife is the economically disadvantaged party
